Not all types of grasslands may be used agriculturally. Out of 16 types of habitats, 10 may be used for production, the others are biologically valuable. The surface area of permanent grasslands in Poland has markedly decreased during the last decade. Now, they constitute slightly...

The results of this study can provide a theoretical basis for the rational utilization of grassland resources and for the sustainable development of grassland ecosystems in the Burqin forest area. 展开 关键词: ALTAI Mountains GRASSLAND plants GRASSLANDS PLANT communities PLANT species diversity ALTITUDES...
the spatial characteristics of grasslands degradation. The ArcGIS 9 software was used to convert data types and do the overlay, reclassification and zonal statistic analysis. Results show that grassland degradation is the most important land cover change in the study area, which occupied 8.24% of ...
DEM (1:250,000) data, roads and settlement data were used to analyze the spatial characteristics of grasslands degradation. The ArcGIS 9 software was used to convert data types and do the overlay, reclassification and zonal statistic analysis. Results show that grassland degradation is the most ...
The coverage, photomass and the basal conditions of the alpine grasslands were improved by establishing mixture grassland of perennial grasses in this region. In 9 combinations of the grasses, Elymus nutans and/or Clinelymus nutans dominated the communities. All the grass communties can be ...
aTo understand the function of the plateau grassland ecosystems under climate change conditions, it is necessary to evaluate and clarify the carbon dynamics in the alpine grasslands. 在气候变化情况下要了解高原草原生态系的作用,评估和澄清碳动力学在高山草原是必要的。[translate] ...
There were contrary change tendency among the quantity,quality and diversity indexes of different grasslands. Artificial grassland was the best effective measure in controlling degraded grassland of rocky desertification,improved grassland was better,and enclosure was the worst. 展开 关键词: rocky ...
Many different types of herbivores and carnivores, and some reptiles and amphibians exist here.Brown forest soils characterize temperate deciduous forest ecosystems. The surface litter layer in these soils is thin due to rapid decomposition. Grassland In central North America are the grasslands, the ...
What is an example of a food chain in the grasslands? An example of a food chain in the grasslands begins with the presence of tall grass. The tall grass is eaten by a herbivore, such as an elk. An elk is eaten by a carnivore, such as a lion. What is the food chain in the pr...
